Abstract (en)

[origin: EP2873475A1] A method of manufacturing wires, including microwires, of Cu-Ag alloys, in particular of alloys of Cu-(3÷7.9)% Ag by weight, consisting in that the materials in the form of high chemical purity copper and silver are melted at a temperature of 1083÷1300 C in a graphite crucible placed in a furnace, and subsequently continuously cast at a temperature of 1083÷1300 C, in an inert gas atmosphere, using a graphite mould, at primary cooling conditions (mould cooling) and secondary cooling conditions (the solidified alloy after leaving the mould). Thus obtained casting is subjected to the thermo-mechanical treatment.
